Help Developing in Web Panels

code3

Why are JavaScript alerts not showing in web panels?
What event to listen for to know when the web panel is opened?

Thank you!

This isn’t really a modification question, it’s an extension question. But maybe the people here would be better able to help.

@code3 But I think (think not know) that it is only possible / much easier with mods – you can just watch the PANEL_STATE (or what was it) in the storage & prolly inject a script.

I don’t know about the alerts.

@potmeklecbohdan I’m making an extension, not a mod. I guess the alternative is to update automatically by broadcasting events.

This fires on panel opening but not closing:

window.addEventListener('resize', () => {
      console.log("Panel opened...");
    });

As long as you don't need to worry about detecting closing as well, then that should work.
